Abstract
Description
Technical Field
[0001] This utility model relates to the field of wave soldering technology, specifically to a wave soldering furnace carrier. Background Technology
[0002] Wave soldering is a process in which the soldering surface of a circuit board comes into direct contact with high-temperature liquid solder to achieve the soldering purpose. The high-temperature liquid solder is kept on an inclined plane, and a special device makes the liquid solder form waves, hence the name "wave soldering". Its main material is solder bar.
[0003] Currently, wave soldering processes have shortcomings in securing electronic components. When electronic components enter the wave soldering oven, they are easily displaced due to factors such as solder flow, vibration during the process, and mechanical stress. This displacement leads to soldering defects, such as cold solder joints and bridging, which seriously affect soldering quality and product yield. Furthermore, due to the diversity of electronic products and the complexity of circuit boards, electronic components of different shapes and sizes require different securing methods and reflow mounts. Existing reflow mounts lack sufficient adaptability to meet the complex and diverse assembly and production needs of circuit boards, leading to frequent mount changes or complex adjustments during production. This affects production efficiency and product consistency and reliability. Additionally, the amount and distribution of flux used in wave soldering are crucial to soldering success. However, current technology has deficiencies in controlling flux, lacking effective blocking methods. This easily leads to excessive flux flowing into the soldering area. Excessive flux interferes with the soldering process, increasing the risk of soldering failure, resulting in product rework and scrap. This not only affects production success rate but also increases production costs, causing significant challenges for enterprises. Utility Model Content
[0004] The purpose of this invention is to provide a wave soldering furnace carrier to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wave soldering reflow carrier, comprising a reflow fixture, a support plate fixed to the top of one side of the reflow fixture, a smooth plate rotating at the top of the support plate, a telescopic pressure rod fixed to the bottom of the smooth plate, a limit plate fixed to the bottom of the telescopic pressure rod, a limit member fixed to the top of the other side of the reflow fixture, a limit groove fixed to the bottom of the reflow fixture, a blocking member sliding inside the limit groove, and a fixing member fixed to one end of the blocking member.
[0006] Preferably, the outer wall of the telescopic pressure rod is provided with a spring that can provide pressure to the limiting pressure plate.
[0007] Preferably, the limiting component includes a supporting vertical plate, and the supporting vertical plate is fixed to the top of one side of the furnace fixture, with a limiting rod sliding inside the supporting vertical plate.
[0008] Preferably, the outer wall of the limiting rod is provided with a spring that enables the limiting rod to be reset and inserted into the limiting hole opened at one end of the smooth rotating plate for limiting.
[0009] Preferably, the blocking member includes a sliding rod, the sliding rod slides inside the limiting slide groove, the sliding rod has a cavity inside, a blocking slide rod slides inside the cavity, and the bottom ends of the furnace fixture are fixed with support slide grooves on both sides. The support slide grooves have a slide channel inside, a slide groove slides inside the slide channel, and a blocking slide rod slides inside the slide groove.
[0010] Preferably, the fixing member includes a limiting plate, a limiting plate is fixed to one side of the sliding groove, a limiting vertical rod slides inside the limiting plate, a limiting block is fixed to the other side of the sliding groove, a cavity is formed inside the limiting block, a driving eccentric wheel rotates inside the cavity, a driving rotating rod is fixed to one end of the driving eccentric wheel, and a sliding insert rod slides inside the limiting block.
[0011] Preferably, the outer wall of the limiting vertical rod is provided with a spring to reset it, thereby limiting the blocking slide rod by multiple limiting holes arranged in parallel on the surface of the inserting blocking slide rod.
[0012] Preferably, one end of the support groove is provided with multiple limiting holes arranged in parallel, which, together with the sliding rod, limit the sliding groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The coordinated operation of the support plate, smooth plate, telescopic pressure rod, and limiting pressure plate provides stable pressure for electronic components. The spring on the outer wall of the telescopic pressure rod can apply downward pressure to the limiting pressure plate according to the actual situation of the electronic components, ensuring that the electronic components are firmly fixed in the reflow fixture during the reflow process. This stable fixing method effectively avoids the displacement of electronic components caused by factors such as solder flow, vibration during the reflow process, and mechanical stress, reducing welding defects caused by component displacement, such as cold solder joints and bridging, significantly improving welding quality, and thus increasing the product yield.
[0015] 2. For electronic components of varying shapes and sizes, the elastic fit between the telescopic pressure bar and the limiting pressure plate automatically adjusts the pressure, ensuring that different components can be properly secured. This enhances the carrier's adaptability to various electronic components, making the reflow carrier suitable for complex and diverse circuit board assembly production, and improving product consistency and reliability.
[0016] 3. The sliding rod and blocking rod in the blocking component form an effective system for blocking the flux. The sliding rod not only provides support for the blocking rod but also limits its travel. The blocking rod can slide within the cavity of the sliding rod, effectively blocking the flux in the wave soldering furnace. By preventing excessive flux from flowing into the welding area, welding failure caused by excessive flux is avoided, ensuring the stability and reliability of the welding process and improving the success rate of production.
[0017] 4. The position of the blocking slide bar can be flexibly adjusted. It can be adjusted according to different welding processes and electronic component sizes. With the coordinated action of the sliding bar, the support slide groove and the sliding groove, the carrier can adapt to different production needs and ensure that it can effectively block the flux in various welding scenarios, reduce product rework and scrap due to flux problems, and save production costs.

The outer wall of the limiting rod 7 is provided with a spring that can reset the limiting rod 7 and insert it into the limiting hole opened at one end of the smooth rotating plate 3 to limit it.
[0031] The blocking component includes a sliding rod 9, which slides inside the limiting groove 8. The sliding rod 9 supports the blocking rod 10 and limits its movement. A cavity is formed inside the sliding rod 9, and the blocking rod 10 slides inside the cavity. The blocking rod 10 blocks the flux inside the wave soldering furnace to prevent excessive flux from causing welding failure. Supporting grooves 11 are fixed on both sides of the bottom end of the furnace fixture 1. The supporting grooves 11 support the sliding groove 12 and limit the movement of the blocking rod 10. A slide is opened inside the supporting groove 11, and the sliding groove 12 slides inside the slide. The blocking rod 10 slides inside the sliding groove 12.

[0032] The fixing components include a limiting plate 13. The limiting plate 13 is fixed to one side of the sliding groove 12, supporting the limiting vertical rod 14 and thus limiting the blocking slide rod 10. The limiting vertical rod 14 slides inside the limiting plate 13.

The spring set on the outer wall of the sliding insert rod 18 resets it, thereby canceling the limitation on the sliding groove 12. The sliding groove 12 moves back and forth, and the sliding groove 12 drives the blocking slide rod 10 to move back and forth to block the electronic components of different gears.
